The disclosure relates to an electron accelerator which is employed for sterilizing packaging material and which is included as a part of an aseptic packaging machine which is initially sterilized by means of an oxidizing chemical sterilizing agent such as H2O2 and steam. The "window" (20) of the electron accelerator, which is covered by a metallic window foil (19), displays a thin coting of glass disposed on the window foil (19) which protects the window foil (19) against chemical action, principally oxidation which the chemical sterilizing agent H2O2 can give rise to. <IMAGE> |
